Hmmm I don't have this experience, rather the opposite.  For
performance tunings I tune the outside string to the middle string,
then the other outside string to the middle string, then listen to the
three strings.  I find I get better unisons doing this than tuning the
outside string to the middle string and then the other outside string
to the two strings tuned.  If I don't like the unison I repeat tuning
each outside string to the middle string.   Sometimes the problem is
one string slipped.  So I check the middle string  to the temperament.
If I still don't like, I find two strings that are the best unison and
tune the third to those.  ---ric
